Do you have an under sink water filter?

I want to purchase an under sink filter that has the best tasting water. Please comment on under sink water filters you have tried. Again, my goal is the best tasting water possible. That is more important than cost although I’m not sure that the most expensive models give the best taste.

    I had an under sink filter but it was a pain to change the filter, nor was the water that good. I now have a Brita, on faucet, filter… it installs easily, easy to change and the water tastes fine. I imagine some under sink filters work better though.

    I guess I should mention that maybe I am a little biased, but I promise not to sell you any specific brand and give a choice.

    I’ve tried, and have seen various undersink installations, from regular single-cartrdige to Reverse Osmosis. There is no "the best" solution, it depends a lot on what’s in your water.

    Let’s start with the taste – generally any system that has carbon-based filter and is capable of removing chlorine will produce a good-tasting water. There may be other contaminants in your water, however, that contribute to bad taste.

    I am not a big fan of undersink Reverse Osmosis units, because of the agressive "acidic" water they produce. It is probably "the purest" water you can find, yet nowhere on earth water exists in pure H2O, and that says something. Plus, it tastes like…nothing.

    The best filtration process in existance is Ultrafiltration, but you will be hard-pressed to find undersink filters that use it. But it is coming soon, in a year or two.

    The next best is multi-stage units. Typically, they use a carbon (carbon block or granular activated carbon) filter, plus a combination filter (those typically contain KDF, a mixture of copper and zync, a micron-size filter, and maybe something else). You may want to add a 3rd filter to take out fluoride, for instance.

    If you don’t have much space under the sink, the smallest undersink filter with at least 2 cartridges I’ve seen is Aquasana’s.
